Overview
About this bike
From exploring gravel roads to checking out those long mountain passes, Opus's Spark 4 loves to take you anyplace you want to go. Its triple-butted aluminum frame is responsive, nimble, and makes short work of whatever surface you're on. Its low bottom bracket, wide tire clearance, and long chain stays ensure stability and comfort all day long. Shimano Claris drivetrain components and cranks equip you with smooth shifting and all the gears you need. Promax disc brakes handle braking duties with finesse and control, while Alex wheels with wide multi-surface tires inspire confidence on rough pavement and gravel roads.
